Atmel's voltage regulator system IC, the ATA6405, is based on a fully integrated system voltage supply concept and consumes extremely low power. The device supports operation of up to 40 V and is optimised for applications in harsh environments. Applications include all kinds of electronic control units (ECUs) to supply the microcontrollers in 12/24 V board voltage systems, for example, climate control, airconditioning or dashboard modules.
This regulator IC is especially suited for applications where linear regulators cause excessive power dissipation and where additional performance such as power management is requested. Since the device is not a standard linear voltage regulator IC but a system device, many application parts are already integrated, eg, reset logic, window watchdog, wake-up mechanism etc. To minimise power consumption, a switching regulator generates a voltage for supplying the internal linear regulator with a 5 V output voltage for microcontrollers.
To monitor the microcontroller, provision has been made for a window watchdog feature incorporating a reset logic function. The voltage system IC provides three modes: active, standby and off. During off mode, quiescent current is under 10 μA, and the output voltage is switched off. In standby mode, quiescent current is under 30 μA while the output voltage of 5 V is still available to operate the microcontroller.
Several protection features such as overtemperature shutdown, full protection against short circuits and over-/undervoltage detection are included. The ATA6405 comes in QFN28 package, which measures 7x7 mm.
